Bluetooth is a standard for wireless communication on short distances. It standarized multiple profiles for different use-cases such as music streaming, serial connections, message exchange, phone calls, and many others. It has been first published in 1994 and since then has been updated several times. The recent version called Bluetooth 5 is a major update and step forward towards the IoT market and it's needs.
Bluetooth is developed and published by the Bluetooth Special Interest Group

- HCI UART, USB, PCMCIA and virtual device drivers
- General Bluetooth and SDP libraries and daemons
- Configuration and testing utilities
